CAN-HEADING MACHINE.

SPECIFICATION forming part of Letters Patent No. 522,270, dated July 3, 1894. s

7 Application filed July 23, 1892. Renewed March 14, 1894. serial No. 503,561. (No model.)

To all whom it may concern.-

Be it known that we, EDWINNORTON and JOHN G. HODGSON, citizens of the United States, residing in Maywood, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Can-Heading Machines, of which the following is a specifi:

cation.

Our invention relates to machines forautomatically applying the heads or ends to the bodies of sheet metal cans.

It relates more particularly to the machine heretofore patented to us in Letters Patent of the United States No. 294,065, of February 26, 18-84.

The object of our present invention is to provide means for automatically applying acid or other flux to the ends of the can body prior to the application of the seaming of the heads thereto; and also to improve and further perfect the mechanism for automatically feeding the heads into position for.applica-' furnished with a pad on its inner face in connection with a trough or vessel for holding the acid or flux, and in which the rim of the disk revolves. The aciding or fluxing device is preferably mounted upon the same reciprocating slide or cross head which carries the head applying piston and the seaming devices, so that one movement of this cross head may serve to apply the flux to the end of one can body and to apply the head to the next succeeding can body.

The means or mechanism employed for holding and truing up the can body while the heads are applied thereto consists, preferably, of two opening and closing half-molds or pockets which surround the can body and true it up into shape to receive the heads by exerting external pressure upon its periphery.

One of these part molds is preferably mounted upon a reciprocating slide or cross head and the other upon an intermittently revolving wheel- This intermittently revolving wheel is provided with a series of part molds upon its periphery, each of which coacts in turn with the reciprocating part mold, and this wheel thus serves as the device for feeding or con veying the can bodies first into position for the application of the flux thereto and then into position for theapplication of the heads thereto. 7 v

The means or device for applying and forcing the heads upon the can bodies consists of reciprocating pistons or plungers which are preferably mounted upon the same slides that carry the seaming devices or jaws.

The seaming devices, especially where the cans to be operated upon are rectangular, preferably consist of reciprocating jaws or dies.

In the accompanying drawings which form a part of this specification and in which similarletters of reference indicate like parts, Figure 1 is a plan view of a machine embodying our invention. Fig. 2 is aside elevation. Fig. 3 is a detail elevation showing the can head feed chute and the can head feed device operating in conjunction therewith. Fig. 4 is a section on line 4-4. of Fig. 3. Fig. 5 is a section on line 5-5 of Fig. 3. Fig. 6 is asection on line 66 of Fig. 3. Fig. 7 is an enlarged detail section taken on line 77 of Fig. l and showing an elevation of the fluxing device. Fig. 8 is a section on line 8-8 of Fig. 7. Fig. 9 is a detail view of the can head chute. Fig. 10 is a section on line 10 10 of Fig. 1. Fig. 1 and Fig. 12 is an elevation of the mechanism for operating the crimpingorsqueezing aws.

In the drawings A represents the frame of the machine.

B are the half-molds or pockets for holding and sizing the can body, which are mounted upon the intermittently revolving wheel B.

C is the reciprocating half mold carried by Fig. 11 is a section online 11 11 of the slide or cross head O which coacts with IOC ing the can heads upon the can bodies, the same being mounted upon the slides or cross heads D.

F F are the clamping or seaming devices, the same consisting preferably of reciprocating slides mounted in suitable guides F on the cross head D.

E is the aeiding or fluxing device consisting, preferably, of a pad or cushion carried by the revolving disk E, the rim of which revolves in a trough or vessel E for containing the flux. 1

G is the can head feed chute or passage along which the can heads are fed into position for application to the body of the can. The can head feed chutes G are mounted upon the same reciprocating cross head D which carries the pistons D, the fluxing device E and the seaming or crimping jaws F. The can head feed chute G is furnished with a reciprocating feed slide g mounted in suitable guides g, the same being furnished with pawls or feed fingers g which are held in place by springs 9 Corresponding spring pawls g are afiixed to the feed chute to prevent the can heads from being withdrawn at the return movement of the can head feed slide g. The base or lower end G of the can head feed chute corresponds in size to the can head and registers accurately in line with the can body holding and sizing device B C, so that these two devices G and B C serve to register the can head and can body accurately in line with each other at the time the body and head are forced together by the pistons or plungers D. The squeezing jaws F also may serve as a means for registering the can head and can body together and to cause the flange of the can head to pass around the end of the can body evenly and uniformly, as they are mounted on the cross head D concentric with the base G of the can head chute.

So far as performing the function of applying the can head to the can body is concerned, the base G of the can head chute and the squeezing jaws F may both be considered as forming a continuation of the mold B C by which the can bodyis held and sized in position to receive the heads.

The intermittently revolving wheel B which carries the part molds B is operated by a ratchet B on the shaft B of wheel B, which is engaged by a pawl 13 pivoted to a swinging arm 13 which is operated from the crank shaft K by means of the crank K thereon, connecting link K lever K and connecting link K extending from the lower arm of said lever K to said swinging arm B The wheel B is locked in position by means of a looking pawl or bolt I) which engages a notched rim 0 on the shaft of said wheel B. The locking bolt 1) is withdrawn at intervals by means of a cam or projection 12 on the swinging arm The locking bolt Z) is secured to a reciprocating slide b having a pin or projection b with which the cam or projection b on the swinging arm 13 comes in contact when said arm B is drawn back by the connecting link K, as before described, into position for causing the pawl 13 to engage the next tooth of the ratchet B and turn the wheel B another step. The cross head 0 which carries the reciprocating part mold O is operated by cams O O on the crank shaft'K.

The cross heads D which carry the pistons D, fluxing devices E, the seaming devices F and the can head feed devices Gr g are reciprocated back and forth by means of cams D" on the conntershafts D said countershafts D being connected by beveled gears (Z cl with the crank shaft K. The crimping jaws F are reciproeated in their guides F on the cross head D by means of cams F F on the crank shaft K which operate the slide Feonnected by a link F to one of said crimping jaws F; and the remaining crimping jaws are operatedfrom this crimping jaw by means of the connecting links f and crank shafts f which are pivoted to the cross head D and which crank shafts are furnished with eccentrics for operating the slides F. The can head feed slides g are operated by cams G G on the countershaft G whieh engagea bell crank lever G pivoted at G to the frame, the upper end of which is pivoted at g to a pivoted link g to which is pivotally connected a second link 9 which is connected at its opposite end to the slide 9 bya swiveling coupling g By this double link and double pivoted connection of the operating lever G to the feed slide g, the radial movement of the operating lever is compensated for, while at the same time the feed slide is permitted to have its necessary transverse movement with the cross head D upon which it is mounted.

The fluxing device E is given a step by step revolving movement by means of a ratchet E which is operated by a pawl E pivoted to a swinging arm E which is actuated by a link E from the crank E the shaft E of which is revolved by a gear E which meshes with a gear E on the shaft of the intermittently revolving wheel B.

The can bodies are delivered to the can body feed wheel B by a feed belt or conveyer II.

V The can head feed chute G at the upper portion thereof beyond the can head feed slide 9 which receives the loose heads is provided on opposite sides alternately with can shaped projections g" which serve to twist or tilt two adjoining heads in the chute into crossing or intersecting planes for the purpose of preventing one head lapping or slipping beyond another and wedging in the chute. This isclearly illustrated in Figs. 2 and 9. The flanges on the can heads are IOO gravity. It will of course be understood that the projections g are'located the width or diameter of the can head apart so that one projection will operate upon "one can head and the other projection operate on the-succeeding can head and thus tilt the two so that they will cross each other.
